<div class="section"><h4 class="sectiontitle">背景信息</h4><p><span>OceanProtect</span>支持使用备份副本、复制副本（不支持恢复至原云服务器）、反向复制副本、归档副本（复制副本的归档副本不支持恢复至原位置）进行云磁盘恢复，支持恢复至原位置或新位置。级联复制副本及其归档副本不支持恢复到原云服务器。</p>
<ul><li>恢复至原位置<p>恢复到当前云平台的云服务器磁盘，包含已有磁盘和新建磁盘。</p>
</li><li>恢复至新位置<p>恢复到其他云服务器的已有磁盘。</p>
</li></ul>

<div class="section"><h4 class="sectiontitle">注意事项</h4><p>由于代理主机最多允许挂载24块磁盘，因此在做备份恢复时，如果代理主机已挂载了24块磁盘，系统将等待有空闲槽位时再执行恢复任务。</p>
